Perfectionism never delivers on its promise of perfection. It does not work.
Some psychologists use the phrase "creative hopelessness" to describe the moments when we realize that our psychological strategies are useless or counterproductive. To arrive at creative hopelessness, write down your reason for maintaining your perfectionism. It'll probably be something like this:
If I try hard enough and I'm very careful and I follow all the rules, everything will go right and everyone will love me and I'll feel good all the time.
Now ask yourself the following question, made famous by our good friend Dr. Phil: So, how's it working for you?
The most common response I get when I ask this question, whether I'm addressing myself or a client, is laughter. Releasing our doomed, anxious hope for perfection opens us to the joy available in our actual lives—especially if we move on to the next exercise.
